SUMMARY: The Visual DSD (DNA Strand Displacement) tool allows rapid
prototyping and analysis of computational devices implemented using DNA strand
displacement, in a convenient web-based graphical interface. It is an
implementation of the DSD programming language and compiler described by Lakin et
al. (2011) with additional features such as support for polymers of unbounded
length. It also supports stochastic and deterministic simulation, construction of
continuous-time Markov chains and various export formats which allow models to be
analysed using third-party tools.
